Abstract
The utility model discloses a kind of Anti-loose locking nuts of wind driven generation set main shaft bearing, including nut body, the internal thread of the nut body, which is divided to, plastic whorl and two sections metal threaded, and the screw pitch of the plastic whorl is less than metal threaded screw pitch, its hardness is less than the external screw thread hardness on main shaft, during nut is tightened, it is described metal threaded to be first screwed into main shaft, and main shaft is screwed into after the plastic whorl, by the deformation of plastic whorl, makes nut and principal shaft locking and achieve the purpose that locking.The utility model is locking using the deformation of plastic whorl, will not destroy the helicitic texture of locking nut counterpart, and do not have to stove bolt, without fluting, processing cost is low, and dismounting is also convenient for.
Description
Technical field
The utility model is related to the locking technical fields of wind driven generation set main shaft bearing lock nut, refer in particular to one kind
The Anti-loose locking nut of wind driven generation set main shaft bearing.
Background technology
Wind driven generation set main shaft bearing lock nut is relatively large in diameter, generally higher than 600mm, for the anti-of major diameter nut
Loose measure is that a ring recess 01 is opened on screw thread, as shown in Figure 1, after stove bolt is tightened, the screw thread on locking nut deforms,
Locking to make locking nut achieve the effect that, 02 tightens position for stove bolt in figure, and locking principle is in locking nut screw thread
Side is slotted, and in place by locking nut screwing first, then stove bolt is tightened, since the effect of stove bolt makes the width of slot become smaller, is made
The screw thread of locking nut and the screw thread of main shaft deform, and achieve the purpose that locking.Such locking disadvantage is：1, locking is destroyed
Screw thread on nut and matched main shaft, spindle thread and locking nut deformed threads；2, using stove bolt, increase cost；
3, a ring recess, high processing costs are processed at locking nut inside thread；4, due to spindle thread and locking nut deformed threads,
Locking nut dismounting is difficult.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, it is proposed that a kind of wind driven generation set main shaft bearing
Anti-loose locking nut, the Anti-loose locking nut are locking using the deformation of plastic whorl, will not destroy locking nut
The helicitic texture of counterpart, and do not have to stove bolt, without fluting, processing cost is low, and dismounting is also convenient for.
To achieve the above object, technical solution provided by the utility model is：A kind of wind driven generation set main shaft bearing
Anti-loose locking nut, including nut body, the internal thread of the nut body, which is divided to, plastic whorl and metal threaded two
Section, and the screw pitch of the plastic whorl is less than metal threaded screw pitch, hardness is less than the external screw thread hardness on main shaft, in nut
During tightening, it is described it is metal threaded be first screwed into main shaft, and be screwed into main shaft after the plastic whorl, pass through the change of plastic whorl
Shape makes nut and principal shaft locking and achievees the purpose that locking.
The plastic whorl is cast.
The utility model compared with prior art, has the following advantages that and advantageous effect：
1, locking using the deformation of plastic whorl, spindle thread structure will not be destroyed.
2, since spindle thread does not destroy, the service life of main shaft is improved.
3, do not have to stove bolt, reduce cost.
4, fluting is not had to, direct pouring is molded, and processing cost is low.
5, spindle thread is indeformable and plastic whorl intensity is low compared with metal, therefore convenient disassembly.
Description of the drawings
Fig. 1 is conventional fan main shaft bearing locking nut sectional view.
Fig. 2 is the Anti-loose locking nut sectional view of the utility model.
Specific implementation mode
With reference to specific embodiment, the utility model is described in further detail.
It is shown in Figure 2, the Anti-loose locking nut for the wind driven generation set main shaft bearing that the present embodiment is provided, packet
Nut body 1 is included, the internal thread point of the nut body 1 has plastic whorl 11 (being located at left side in figure) and metal threaded 12 (position
The right side in figure) two sections, and the pitch P of the plastic whorl 112Pitch P less than metal threaded 121, hardness is less than main shaft
On external screw thread hardness, 11 part of plastic whorl is by casting.
During locking nut screwing, metal threaded 12 are first screwed into main shaft, after metal threaded 12 are all screwed into, plastic spiral
Line 11 just starts to be screwed into main shaft, due to the pitch P of plastic whorl 112Pitch P less than metal threaded 121, therefore 11 meeting of plastic whorl
It deforms, it is locking to achieve the purpose that.Due to being more than with the external screw thread hardness on the main shaft of locking nut screw-internal thread fit
Plastic whorl 11, thus plastic whorl 11 deforms and metal threaded on main shaft will not deform.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore change made by all shapes according to the utility model, principle, it should all cover in the scope of protection of the utility model
It is interior.
Claims (2)
1. a kind of Anti-loose locking nut of wind driven generation set main shaft bearing, including nut body, it is characterised in that：It is described
The internal thread of nut body, which is divided to, plastic whorl and two sections metal threaded, and the screw pitch of the plastic whorl be less than it is metal threaded
Screw pitch, hardness be less than main shaft on external screw thread hardness, during nut is tightened, it is described it is metal threaded be first screwed into main shaft,
And main shaft is screwed into after the plastic whorl, by the deformation of plastic whorl, makes nut and principal shaft locking and achieve the purpose that locking.
2. a kind of Anti-loose locking nut of wind driven generation set main shaft bearing according to claim 1, feature exist
In：The plastic whorl is cast.
